Title: Exciting open type electromagnetic brake device
Inventor: FUKUNAGA CHIAKI
IPC: B60T13/74
Filed: 1979-11-06
Abstract: PURPOSE: To prevent the delay of braking work as well as simplify a circuit by a method in which an electromagnetic brake is connected in series to an AC motor and an electronic switch is operated according to the presence or absence of terminal voltage of the motor to close or open the circuit of the electromagnetic brake.  
     CONSTITUTION: When a contactor 8 is closed, current flows through a rectifying element 12 to a motor 7 when power source side is positive, and also when the power source side is negative, current flows in a transistor 10 because a base current flows through a resistance 11. In the motor 7, AC current flows and also in an electromagnetic brake 9, a half-wave rectified DC current flows, so that at the time of start-up, the brake 9 is excited by the starting current and the release of the brake 9 is made rapidly. When the contactor 8 is opened, voltage is induced by the inductance of the brake 9 but no voltage is applied between the base of the transistor 10 and the emitter, so that the transistor becomes unconductive, the circuit of the rectifying element 12 is released, and the accumulated energy of the brake 9 is lost by discharge through a protective element 3.
